Application filed May 9, 1912. Serial No. 696,080.

Patented Sept. 22, 1914..

To all whom it may concern Be it known that I, CLARENCE F. CoLBERT, aresident of Hoopeston, in the county of Vermilion and State of Illinois,have invented certain new and useful Improvements in Tipping-Machines,of which the following is a full, clear, and exact description.

The invention relates to tipping machines, for closing thevent-perforations in the tops of cans or the caps thereon.

:One object of the invention is to provide an improvedtipping machinewhich is adapted for rapid operation so that it is capable of tipping alarge number of cans.

Another object of the invention is to provide an improved tippingmachine which is simple in construction and efficient in operation. a

Another object of theinvention is to provide improved tipping devices inwhich the soldering point is surrounded by a gas chamber and is heatedfrom the outside thereof to effectively and uniformly heat the point,

to render it efficient in soldering.

Lastly the invention designs to provide a tippingmachine of improvedconstruction and operation.

The invention consists in the several novel features hereinafter setforth and more particularly defined by claims at the conclusion hereof.H

In the drawings: Figure 1 is a front elevation of a machine embodyingthe inven- 35 tion. Fig. 2 is a vertical section taken on line 22 ofFig. 1. Fig. 3 is a horizontal section taken on line 3-3 of Fig. 1. Fig.4: is a detail plan, parts being shown in the section, of thesolder-feeding device. Fig. 5 is a front view of the solder-feedingdevice. Fig. 6 is a section taken on line 66 of Fig. 4:- Fig. 7 is afront view of thetrack for guiding the tipping devices, the carryingarms for said devices being shown in the track. Fig. 8 is a verticalsection through the tipping device carrier showing the chamber forsupplying gas to the tipping devices. Fig. 9 is a detail section of oneof the tipping points and its carrying arm. Fig. 10 is a plan view ofone of the tipping devices. Fig. 11 is a section taken on line 1111 ofFig. 9. Fig. 12 is a detail of the lock for the jacket around thesoldering point.

The machine is adapted to close the vent holes in cans a which are movedin alongitudinal plane by the endless carrier 7) which 1s provided withpins 0 for engaging the cans. Carrier 6 is operated by an endless chaln(Z, 1n manner well understood in the art, and travels upon tracks 6which are sustalned in any suitable manner.

The supporting structure of the tipping machines comprises a bracket 15which is adapted to be secured to the tracks 6, by a clamp 16 and bolt17, posts 18 which are secured in said bracket, and a cross-head 19extending between and secured to the upper ends of said posts. Guidebars 20 between which the cans are guided against transverse movement tokeep them alined with the rotating tipping devices are each adjustablysustained by a pair of arms 21 and22 extending forwardly and rearwardlyfrom said bars respectively. The outer end: of each of these arms isadjustably secured to a post on a lug 23 on bracket 15, by a screw 24:,and its inner end is pivoted, as at 25, to one of the guide-bars 20. Thepurpose of this guiding-means is to permit both bars to be adjusted toguide cans of different sizes without varying the center of thelongitudinal travel of the cans relatively to the tipping devices, andso that lateral adjustment of the tipping devices will not be necessary.By providing a pair of parallel arms for each bar 20, the, latter willalways be adjusted in parallel relation to the'plane of travel of thecans.

A frame 27 is slidably mounted on posts 18, being provided with sleeves28 through which the posts extend, and this frame is verticallyadjustable on said posts by a screw 29 which extends through the crosshead 19 and is provided with a hand-wheel 30 whereby it may be turned.The reduced lower end 31 is rotatable in a bearing 32 in said framewhich is held between a shoulder on the screw and a collar 33, so thatthe frame will be raised or lowered by turning the screw.

The machine comprises a vertically rotatable series of tipping-deviceswhich are adapted to successively contact with the cans on conveyer b.All of these devices are mounted on and carried by a carrier in the formof a hollow spider 34, which is secured by a screw 35 to a sleeve 36which is jour-' naled in a bearing 37 on vertically adjustable frame 27.This sleeve, is provided with a fixed collar 38 which is held by aflanged combustion.

collar 39 which is secured to hearing 37 so that the sleeve willberotatable and be held against longitudinal movement, in its bear ing.The outer end of this sleeve 36 is open and connects with a chamber 40in bearing 37 and pipes 41 and 42 connected to said j chamber supply gasand air to form the fuel for heating the tipping-points, which fuelpasses through sleeve 36 to the chambers 43 may be hadto the solderlngpoint 52 for hub 48 of an arm 49 which carries a tipping device at itsouter end.

Each tipping. device comprises a hollow shell or jacket 51 and asoldering point 52 which is secured in the shell, extends through thechamber in the shell and has a tapered terminal 53 which is adapted tocontact with a strip of solderand depositit in the vent opening of thecan. The fuel from port 46 in spindle passes through aport 53 inarm'49,under control of a regulating screw 54 whereby the flow of fuelmay be varied. Shell 5]. comprises a removable section 55 provided witha handle 56, and a lug 57,

adapted to fit into a recess in a lug 58; formed'on the section of theshell which is integral with arm 49. A latch 59 is pivoted to a lug 60and is adapted to engage a lug 61 on shell-section 55 to hold thesections together. By removing section 55, access cleaning or.replacement. An opening 60 is formed between the tapered terminal 53 ofpoint 52 and the acket, for the burning of the fuel and escape of theproducts of Fuel will be constantly supplied to all of the solderingdevices rotating with the carrier 34. Each spindle 45 which carries oneof the tipping-devices is pivotally movable in the carrier. The purposeof this pivotal movement is to permit each s0ldering point in the lowerarc of 1ts rotatlon to remain in contact with the cans, by gravity,while the can-tops are moving in a horizontal plane and the solderingdevices are moving in a vertical plane. Resultantly, the solderingpoints may remain in contact with the. can a sufficient period toeffectively close the vent openings,fwhile the cans are traveling inarectilinearpath and the solderingdevices are operated by the verticallyrotating carrier. An'arm 62 is secured to the inner end of each spindle45 and carries a roller 62 adapted to travel in annular track 63which isformed in frame 27. This track is normally disposed to cause thesolderingpoints to contact with the cans before they reach the verticalcenter and vso that after contacting with the can, the soldering deviceswill be free to remain in contact with the can by gravity until thetipping-opera tion has been completed, and for that purpose, a straightportion 64 is formed adjacent the lower portion of the track to releasethe soldering devices and permit theirroll- :ers 62 to be lifted off ofthe outer flange of the track by the cans. After each device'hascompleted a tipping-operation,'it will be guided against pivotalmovement in, either direction by the inner and outer flanges of thetrack. The lower portion of the outer flange of the track serves tolimit the movement of the'soldering-devices in the event no can is fedthereto. 7 v v Continuous rotary movementis imparted to the carrier 34by gearing comprlslng a gear-wheel 66 fixed on sleeve 36 by'scr'ew .67,a gear-wheel 65f meshing with gear Y66 and secured to a vertical shaft"68 which is mounted in a bearing 69 in frame 27 and in bearings 70 and71 'onfbracket 15, and a worm-gear 72 through which said shaft extendsand which is operatively connected thereto by key 73 and an elongatedgroove 74 in the shaft. Bearings 70 and 71 confine worm-gear 7 2against'movement with shaft 68 so that said shaftmay beadjustedflvertically with the frame 27, key;7 3 and. groove 7 4beingadapted to maintain operative consection to drive the shaft in its,different vertical positions. Worm-gear 72 is driven by a worm-pinion 75on a'shaft'77 which is journaled in bearings 76 on bracket 15 and towhich movement is imparted in syn- ,chronism with the conveyer b tocause the speed of the tipping-devices to correspond to the movement ofthe cans. the carrier for the tipping-devices will be constantly driven,one of said devices being adapted to tip each can as it passes there:under. This mechanism thus exemplifies a tipping-machine infwhich thereis a series of vertically rotating tipping devices adapted tosuccessively engage the cans and which is adapted for rapid operation.The machine alsoexemplifies one in which tippingdevices may becontinuously rotated.

A device is rovided for feeding solder into the path of the rotatingtippingpoints to cause the solder to be fed each time that thetippingkpoint removes its end portion. Since the carrierandtipping-devices are constantly operated whether or. not a can is presentbeneath the tipping-devices the solder feed is controlled by the cans sothat if no can is passing beneath the tipping: devices, no solder willbefed to the point and in this manner, the necessity of providingcan-controlled driving mechanism for the solder, feed arises,solderefeeding Result antly 7 device comprises a pair of rolls 80 and81,

.movement'is imparted to roll 80, which is journaled upon a stud 83secured in frame 27, by a pawl 84: which is pivoted to the end of an arm85 on a sleeve 86 which is journaled on stud 83 and is provided with asegmental rack 87. A spring 88 is applied to hold pawl 84: in engagementwith a ratchet 90 onroll 80. spring-pressed dog 89 is applied to holdratchet 90 and roll 80 against retraction. An arm 9l which is secured toa vertical rock-shaft 92 is provided with a rack 93 meshing with rack87, and.

shaft 92 is operated to retract pawl 84 by an arm 94 which is adjustablysecured to shaft 92 by a clamp 95 and has a cam 96 disposed in the pathof travel of the cans,

so that arm 91 will be operated to retract pawl 841- only when a can isbeing fed to the tipping machine. Such retraction brings a roller 97 onthe arm 91, into the path of a tappet-wheel 98 which is secured tovertical drive-shaft 68, so that when a can is present on conveyer b itwill operate arm 94 to set the solder-feeding devices into position tocause arm 91 to be operated to :turn roll 80 and feed solder, by one ofthe tappets of wheel 98. Each tappet will engage roller 97 and operatethe feeding-device to cause the end of the strip of solder to be wipedby the tipping-point just before wit passes into engagement with the canwhich is operating arm 94. Roller 81 is mounted upon an arm 100 which ispivoted to a stud 101 connected to frame 27 and a screw 102 passingthrough 3, lug 103 on the frame is adapted to adjust the arm to causethe strip of solder to be firmly gripped between rolls 80 81 and to befed forwardly thereby. I This solder-feeding mechanism thus exemplifiesone which is controlled by cans passing to the tipping-devices andwhereby solder will be fed to the tippingdevices only when a can ispresent on the conveyer, and this mechanism is particularly adapted fora tipping machine in which the tipping devices are continuously drivenwhen operated.
